Our customers are able to use this groupware solution to connect to Active Directory and OpenLDAP, although Postgres support would be an improvement.
Zarafa has several very valuable features, among them a very good Outlook-like web interface. Furthermore, ZPush for talking between ActiveSync and mobile devices is a valuable asset. In addition, one is able to connect via Outlook and the exchange protocol to Zarafa. This makes Zarafa a free, and working, alternative to Microsoft Exchange.

One of the premium features was customized rooms tailored to the collaboration needs
Zimbra's strength lies in its individuality, and it should focus on leveraging its unique features rather than trying to emulate competitors. My organization has certified Zimbra technicians, so we believe we can utilize Zimbra certification. However, I was recently informed by Zimbra that no such certification exists. I have recently completed the test kit, and after the training, I will gain access to tickets. Therefore, if any clients are experiencing issues, we have a certified technical team available to provide support 24/7. This is how we can cater to our client's needs. I recommend Zimbra to small-scale and enterprise customers. Anyone, even those with 5 users, can opt for Zimbra. Overall, I rate the solution a nine out of ten.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"This makes Zarafa a free, and working, alternative to Microsoft Exchange."
"Zimbra Collaboration is mainly used for messaging, emails, calendars, video conferencing, and document sharing."
"Zimbra Collaboration's sharing features are most valuable."
"We can control all the data in my IT infrastructure."
"The solution is easy to implement."
"One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software."
"The logs, troubleshooting, and tracking we have found to be the most valuable features, and when we have any issues with lost messages these features are useful because it is very easy to track and log."
"Premium features, such as auto discovery and archiving, mobile management and HSM, make life much easier."
"Most valuable to us is the fact that it's open source, so it's possible to do a lot of customization."
 

Cons

"Not really, although the Zarafa-index component was using a lot of memory and disk I/O bandwith."
"The installation is not straightforward, it can take two days for the full implementation."
"There can be difficulties resolving problems on the server side when problems arise."
"The solution could improve by making it easier to use."
"There are some security issues."
"We had a couple of issues with stability, but nothing that I couldn't work around or fix myself. Zimbra is a powerful product, but since VMware bought it, changes and bug fixes have been very slow in coming."
"Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client."
"The installation is not straightforward, it can take two days for the full implementation."
"Zimbra Collaboration's video conferencing could be improved."
